Air source heat pumps in Middle Assendon
Air source heat pumps collect heat from outdoor air and bring it inside, using electricity to drive the process. It works on the same principle as air conditioning, run the other way and the Energy Saving Trust notes that air-to-air heat pumps are sometimes referred to as air conditioning. Typical jobs include deciding which kind of heat pump suits the home and questions about listed buildings or conservation areas, across radiator systems, underfloor heating and air-to-air heat pumps.
In a place like Middle Assendon, some homes are listed, because permitted development doesn’t apply within the grounds of a listed building, so we check consent first.
Aftercare is simple, and most of it is in the manual: keep the outdoor unit clear, follow the manufacturer’s guidance on cleaning and book a service at the interval they recommend. That also helps where the warranty terms ask for regular servicing.

Keeping the system healthy
How well a system lasts depends on use and care. We suggest:
- Diary the next service
- Avoid switching the heat pump on and off often
- Ask about the grant before you commit
Handover includes the controls and how to get the best from a heat pump. Steady running suits a heat pump better than switching on and off so we set the controls up with you.
Book a service every year. Your manufacturer’s warranty terms may say something about servicing.

Common questions in Middle Assendon
Will a heat pump in Middle Assendon need planning permission?
It depends on the property. Historic England lists about 8 buildings and structures within half a mile of the centre of Middle Assendon. On a house, an air source heat pump can often go ahead under permitted development, with an outdoor unit of no more than 1.5 cubic metres and an installation that meets MCS 020(a), which includes a noise check. Those rights don’t reach the grounds of a listed building, and conservation areas rule out walls or roofs facing a road. If that might affect you, we ask Buckinghamshire council, which is normally the planning authority for Middle Assendon.
Is Middle Assendon within the area you cover?
Yes, smaller places are covered as well as towns. A few photos and the postcode are enough to get things started.
Who has to arrange F-Gas leak checks?
The operator of the equipment, working with qualified engineers. Systems below 5 tCO2e fall outside the set leak check intervals, while larger ones need checks at least every 12 months, or every 6 months from 50 tCO2e. We’ll work out which band applies to yours.
How soon will you get back to me?
You’ll hear from us the same working day. If it’s an emergency, ring the 24/7 line instead.
What accreditations do you have?
F-Gas company certification, NICEIC approval for electrical work and MCS certification for heat pumps, plus Checkatrade membership. Engineers who handle refrigerant hold their own F-gas qualifications as well.
Do you protect the property while you work?
Floors and furniture near the work are covered with dust sheets before work begins, and we tidy up as we go. Before we leave, we clear up and run through the work with you.
What’s the difference between air-to-water and air-to-air heat pumps?
Air-to-water suits homes with radiators and a cylinder; air-to-air suits rooms that need heating and cooling, and we help you choose. Both are part of what we install.

Wherever the system can be run before we leave, we run it and check it in operation.
